; Tests the name mangling performed by the codepath following
; getMangledTypeStr(). Only tests that code with the various manglings
; run fine: doesn't actually test the mangling with the type of the
; arguments. Meant to serve as an example-document on how the user
; should do name manglings.

; Exercise the most general case, llvm_anyptr_type, using gc.relocate
; and gc.statepoint. Note that it has nothing to do with gc.*
; functions specifically: any function that accepts llvm_anyptr_type
; will serve the purpose.
